Smart Bike Helmet Review: Base Camp SF999 vs Livall BH51M NSO

UPDATE: after just a few hours on youtube, my obscure helmet video had received 10 views and 7 comments. All seven were very obvious spam from Base Camp and have been reported and removed. I am changing the settings to hold all comments for review. I can not recommend anyone buy from this vendor based on this behavior.
I review two smart bike helmets, the Base Camp SF 999 and the Livall BH51M NSO. Both of these helmets offer integrated lights and speakers. Both of them are getting returned to Amazon.
The Base Camp's speakers are unlistenable. It also lacks an app that would allow you to use it if the control device is lost or damaged. Outside of these two issues it is a very good budget smart helmet.
The Livall is an excellent helmet but the connection failed repeatedly and I was only able to get it to work one time before it stopped reconnecting. It also suffers from dim lights, no ability to keep the lights on full time, and a proprietary charging cable.
